Product Overview
Acti9 Pro iDPNN-S miniature circuit breakers are modular protection devices designed for low-voltage terminal circuit protection and control. They are mainly used in residential buildings, commercial facilities and industrial low-voltage distribution systems. The product adopts a 1P+N configuration, allowing simultaneous disconnection of phase and neutral conductors, while the neutral conductor does not provide protection functionality. The device provides short-circuit protection, overload protection and isolation protection functions, effectively improving the safety and reliability of terminal circuits. Acti9 Pro iDPNN-S supports C curve and D curve tripping characteristics, allowing users to select suitable protection according to different load types. The rated current range is 2~40A, the rated operating voltage is 230V AC, the rated breaking capacity reaches 6000A, and the service breaking capacity Ics reaches 100%. The product adopts DIN 35 mm standard rail mounting and supports flexible installation direction from 0° to 360°. The device provides IP20 protection degree, and can reach IP40 when installed inside a distribution enclosure. It is suitable for lighting circuits, socket circuits, terminal distribution boards and general industrial control applications. Acti9 Pro iDPNN-S complies with GB10963.1 and IEC 60898-1 standards, providing a reliable and efficient protection solution for low-voltage terminal distribution systems.
